TIRE.

Specification 0f Letters Patent.

Patented J une 23, 1914.

Application filed September 5, 1913. Serial No. 788,205.

To all whom it may concern.' l

Be it' known that I, HARRY WOOD, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inTires, of which the following is a specification.

My invention relates to improvements in tires, the object of theinvention being to provide an improved tire in which a metal armor issecurely held, rendering the tire` puncture-proof yet not materiallyaffecting the resiliency thereof.

A further obj ect is to provide in the tread portionof a shoe or tire, ametal ring preferably made in hinged sections secured at opposite sidesby sections of hard rubber with sections of soft rubber, all of saidparts vulcanized together forming in effect a single integral mass.

With these and other objects in view, the invention consists in cert-ainnovel features of construction and combinations and arrangements ofparts as will be more fully hereinafter described and pointed out in theclaims.

In the accompanying drawings: Figure 1 is a view in side elevationillustrating my improved tire. Fig. 2 an enlarged view in section on theline 2-2 of Fig. l. Fig. 3 is a fragmentary view in section on the line3-3 of F iff. 2. Fig. 4L is a plan view of two sections of the metalring, and Fig. 5 is a side elevation of one section of the metal ring onan enlarged scale.

l represents a. shoe of the ordinary type inclosing an inner tube 2, andlocated in a rim 3 on a wheel felly 4, and I would have it understoodthat while I illustrate an ordinary type of shoe and tire, that myinvention is not limited in this respect.

5 represents a sectional metal ring. This ring 5 comprises a pluralityof sections 6, all sections being precisely alike and connected at theiradjacent ends by hinge pins 7, and provided on their inner and outersurfaces with webs 8. The metal ring 5 is provided on its outer surfacewith a thickness of hard rubber 9 which connects the metal with a. softrubber tread 10. The inner surface of the metal is connected by athickness of hard rubber ll with a thickness of soft rubber 12, whichconnects with the shoe. The shoe is preferably of the ordinary type withits canvas reinforcement, so that the soft rubber thickness 12 operatesto rigidly connect the parts together.

As seen most clearly in Fig. 3, it will be noted that the thicknesses ofhard rubber 9 and ll are provided with spaces at opposite sides of themetal ring at the hinge pins 7, so that the metal ring is free to bendor give so as not to affect the resiliency of the tire.

In constructing the tire, the parts are all vulcanized together, thehard rubber 9 and l1 operating as a binding agent to rigidly connect theSoft rubber at both' sides of the metal ring to the metal ring, andWhile I have illustrated longitudinal webs 8, I would have it understoodthat the surface of the metal may be made in any desired way which willafford a permanent grip for the hard rubber. It will therefore be notedthat the shoe l is provided with a tread containingr a metal ring whichis permanently connected to an outer soft rubber tread l0 and to theinner shoe by a soft rubber thickness 12 by means of the hard rubber atboth sides of the metal ring and by reason of this structure, I renderthe tire practically punctureproof without destroying the resiliencythereof, and constructthe tire in which all of the parts are permanentlyadhering one to the other tc produce 'in effect an integral structure.

Various slight changes might be made in the general form and arrangementof parts described Without departing from my invention, and hence I donot limit myself to the precise details set forth, but consider myselfat liberty to make such changes and alterations as fairly fall withinthe spirit and scope of the appended claims'.

Having thus described my invention, What I claim as new and' desire tosecure by Letters Patent is: i

l. A tire having a metal ring embedded in its tread portion with hardrubber at inner and outer surfaces thereof, said metal ring composed ofsections hinged together, and said hard vrubber formed in sectionsspaced apart at opposite sides of the hinge connection of the ringsections, substantially as described.

A tire having a metal ring embedded in its tread portion with hardrubber at inner and outer surfaces thereof, soft rubber adl In testimonyWhereofl have signed my jacent the hard-rubber, all of said partsvulname to th1s speclcatloh m the presence cnnzed together, said metalring composed of two subscribing Witnesses.
